Running GAUDI jobs is quite easy with
gaudi run /path/to/some_file.gaudi-input
To learn how to create input files, go to Input files, and make sure to check the tutorials!
After the job is completed, you can check the results with
gaudi view /path/to/some_file.gaudi-output
Both tools support lazy-load, filtering and sorting, so choose whichever you prefer. A quick tutorial on GaudiView is available here:
